Pulse pressure conduction structure, portable blood pressure detection module and intelligent wearable device

Abstract

The invention provides a pulse pressure conduction structure, a portable blood pressure detection module and an intelligent wearable device. The pulse pressure conduction structure comprises a shell and a pulse pressure conduction part, wherein the pulse pressure conduction part and the shell or a fixed part fixed on the shell are enclosed to form a cavity for air inflation; and at least one part of the pulse pressure conduction part is capable of directly or indirectly acting on a detection part of a to-be-detected object during air inflation. The pulse pressure conduction part does not need to be wound on a limb, and the applicable part is not limited, so that the pulse pressure conduction part is not limited to arteries of a wrist or an arm, and can be applied to other parts, such as cervical arteries and the heart. After large-volume airbag and cuff after omitted, the pulse pressure conduction structure can be manufactured very small and can be integrated to the portable blood pressure detection module, so that the pulse pressure conduction structure can be independently attached to the to-be-detected part or easily attached to other wearable devices, and meanwhile, a detection space is also provided for other life sign parameter detection devices.

Description

technical field [0001] The invention relates to a blood pressure detection device, in particular to a pulse pressure conduction structure of the blood pressure detection device. Background technique [0002] Arterial blood pressure is the most important and commonly used measurement parameter in clinical practice, and blood pressure is also a component in the risk score of various important cardiovascular diseases, so the measurement of blood pressure has important significance in medicine. [0003] Most of the current non-invasive electronic sphygmomanometers use the oscillometric method, and some use the auscultation method. Both the oscillometric sphygmomanometer and the auscultatory sphygmomanometer are cuff sphygmomanometers. Wherein, the cuff includes a cloth bag and an airbag, and the length of the airbag is generally required to be approximately 0.8 times that of the limb, and the width of the airbag is 0.4 times that of the limb. When measuring blood pressure, wra...

AI Technical Summary

Problems solved by technology

[0004] The problem with this cuff-type sphygmomanometer is that the cuff (airbag) needs to be wound on the limb during use, and the use position is limited, and it is troublesome to use.

At the same time, since the entire circumference of the wrist or arm is occupied, it is difficult to realize the equipment that needs to simultaneously detect vital sign parameters other than blood pressure (such as detecting heart rate by photoelectric method)
